United States Patent FOUNTAIN PEN Jack Rogers, Cincinnati, OhioApplication January 14, 1955, Serial No. 481,834

2 Claims. (Cl. 120-46) The present invention relates to new and usefulimprovements in fountain pens designed particularly for use in markingleather and for other purposes.

An important object of the invention is to provide an inwardly andoutwardly slidable tubular point for the pen and to which flow of ink iscontrolled by a spring biased valve opened to feed ink from the barrelto the point by pressure of the point against the writing or markingsurface.

Another object is to provide an expansible and contractible barrelhaving a pair of spring biased valves therein, and with one valvecontrolling feeding of ink from the barrel to the point and actuated byan inward movement of the latter and the other valve controllingemptying and filling the barrel by the expanding and contractingmovement of the barrel.

A further object is to construct the pair of valves for coaxial slidingmovement, one within the other, and supporting the emptying and fillingvalve on the slidable point and in a position engaging the ink feedingvalve to actuate the latter while maintaining the former closed.

A still further object is to provide a fountain pen of simple andpractical construction, which is efficient and reliable in operation,relatively inexpensive to manufacture and otherwise well adapted for thepurpose for which the same is intended.

These, together with other objects and advantages which will becomesubsequently apparent, reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view;

Figure 2 is an enlarged fragmentary longitudinal sectional view showingboth valves closed;

Figure 3 is a similar view showing the feeding valve open and theemptying and filling valve closed; and

Figures 4, and 6 are transverse sectional views taken respectively onthe lines 44, 55 and 6--6 of Figure 2.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of my invention,the numeral 5 designates a barrel of expansible and contractible plasticor other suitable collapsible material and to the front end of which isthreadedly connected a rigid head 6 having a tapered tip 7 and formedwith a bore 8 in which a tubular point 9 is slidable inwardly andoutwardly at the tip of the head. The outer or front end of the point isformed with a restricted ink delivery opening 10.

The inner or rear end of the point is solid and forms a valve stem 11for a conical valve 12 integrally formed with or suitably secured on thevalve stem.

The valve stem 11 is slidable in a bore 13 at the solid rear end of ahollow valve stem 14 having a disk-type valve 15 at its front end andformed with a valve seat 16 at its front surface engaged by the valve 12to close Patented Sept 3, 1957 I the front end of valve stem 14. Therear end ofvalve stem 14 is slidable in a central opening 17 in a guidedisk 18 which is threaded at its periphery for attaching inside head 6to the internal threads 19 thereof. Open ings or passages 20 are formedin the guide disk for the free flow of ink from the barrel 5 into head 6and vice versa. Openings 21 are also formed in valve stem 14 immediatelybehind the valve 15. i

The front surface of valve 15 is formed with an annular V-shaped groove22 which forms a valve seat for an annular V-shaped rib 23 formed on aninternal shoulder 24 in head 6 and which defines a chamber 25 in head 6of a diameter substantially greater than that of valve 15 and which ispositioned in the chamberf The hollow or tubular portion of point 9 isformed with openings 26 forwardly of valve 15 for the flow of ink fromthe chamber into the point and vice versa.

A coil spring 27 surrounds valve stem 14 and is held under tensionbetween guide disk 18 and valve 15 to close the latter and a coil spring28 surrounds the rear end of valve stem 11 and is tensionally heldbetween the rear end of valve stem 14 and a pin 29 positionedtransversely at the rear end of valve stem 11.

The pen is filled by dipping the point 9 in an ink supply receptacle,not shown, and then squeezing and releasing the barrel 5 whichalternately creates compression and suction in the barrel 5 and head 6,which together form an ink reservoir. Compression in the barrel 5 andhead 6 is relieved by the valve 12 opening in response to suchcompression in the barrel and head for discharge of the compressionthrough the openings 21, stem 14, valve 15, chamber 25, openings 26 andthe hollow portion of the point 9. The valve 15 opens in response tosuction in the barrel 5 and head 6 and the suction then draws inkthrough the point 9 into the chamber 24, head 6 and barrel 5 until thesuction ceases.

Ink flows from the barrel and head into chamber 25 by pressing thebarrel downwardly to force point 9 inwardly to force valve 12 upwardlyand open valve 15 and the ink will then flow through the openings 26 tothe point.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art it is not desired to limit theinvention to the exact construction shown and described, and accordinglyall suitable modifications and equivalents may be resorted to, fallingwithin the scope of the appended claims.

What is claimed as new is as follows:

1. A fountain pen comprising a barrel having a forwardly extendinghollow head communicating therewith to form therewith an ink reservoir,said hollow head being provided with a tip, said barrel being resilientfor compression and expansion to create compression and suction in saidreservoir, said tip having an ink chamber therein having an openingcommunicating with said reservoir, a tubular spring loaded writing pointextending through said tip and communicating with said chamber fordischarging ink therefrom and filling the chamber in response to suctionin said reservoir, a spring loaded valve in said headnormally closingsaid chamber at said opening and movable into chamber opening positionin response to suction in the reservoir to create suction in the chamberand permit ink in said chamber to pass into said reservoir, said pointbeing slidable inwardly and outwardly of said tip, and means on saidpoint engaging and moving said valve into opening position in responseto inward sliding of said point whereby to permit ink in the chamber topass into said reservoir,
